LUBRICANT PEEP Application filed November 10, 1980. Serial Ho. 494,792.

This invention relates to a pump designed primarily for setting up a circulatlon of lubricant' through a metal-working machine such as a cold header or the like, although it is to be understood that it can be used 1n any typeof machine wherein it is desired to maintain a circulation of a fluid.

it is the general practice in cold headers and the like to provide a pump forforclng a lubricant to the points where it 18 to be used. but these have usually been diflicult of access, and whenever it has been desired to remove the dirty oil or to make repairs 1t has been necessary to shut down the machine and thereby stop production.

An object of the present lnvention is to i provide a pump which is so mounted that it can be readily placed in or removed from the machine with which it is used without stopping the operation of the machine.

A further object is to provide a means for facilitating removal of dirty oil and the sub- -titution of new lubricant.-

VVith the foregoing and other ob ects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the de tails of construction herein described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed Without departing from the spirit of the mvention.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figural is a plan view of a portion of a cold header equipped with the present improvements.

Figure 2 is a vertical section through a portion of the machine taken on line 2-2, Figure 1, the cylinder of the pump being broken away.

Figure 3 is an elevation of a portion of the machine showing the removable pan fastened in position.

Referring to the figures by characters of reference, 1 designates the body of a cold header or.other machine requiring constant lubrication. This machine can include a main shaft 2 for operating a slide 3 and can also include a timer shaft or countershaft 4 receiving motion through suitable gearing from shaft 2.

The body of the machine has an opening 5 5 forthe reception of a pan 6, the front of which is adapted to lap the body 1 and to be detachably secured thereto by bolts 7 extending through ears 8 on the pan. A handle 9 can be located on the front of the pan to facilitate moving it into and out of position. Afpump cylinder 10 is carried by a supporting ame 11 in the pan 6 and has a piston 12, the rod 13 of which is guided in one end of the frame. A lever 14 is fulcrumed on the frame. One end thereof is forked at 15 for detachable pivotal engagement with rod 13, and a spring 16 connects the lever to the frame for holding the piston normally at one limit of its movement. w

A valved inlet pipe 17 having a check valve 18 opens into the cylinder 10 at one end and an outlet pipe 19 extends from said end and has a coupling 20 for detachably securing it to one end of a stationary distributing pipe 21 75 in which is located a check valve 22.

A cam 23 is secured to and rotates with shaft 4 where it can engage lever 14, gradually shift it to retract the piston 12 against the action of spring 16, and then release the lever abruptly for actuation of the piston and lever by the spring.

The pan 6 is to be supplied with clean oil and then slid back into the opening 5. This will'bring the end of lever 14 into the path of cam 23 which, in the structure illustrated, rotates in a counterclockwise direction. By reaching through one or more openings in the body 1 the coupling 20 can be manipulated to join pipes 19 and 20. Thus as the :shaft 4 revolves the cam willsuccessively shift and release lever 14 so that spring 16 which is alternately placed under tension and released, will operate the piston to force lubricant intothe pipes 19 and 21s Every time the piston is retracted by lever 14 a supply of lubricant is drawn into'the cylinder from pan 6.

After the lubricant has passed over or through the parts to be lubricated it will be returned to the pan 6 by any suitable means which can include a delivery spout 24. The lubricant can thus be used repeatedly. After it becomes dirty andnnfit for further use the coupling can be disengaged from one of the pipes 19 and 21 and the pan after being detached at 7 from the body 1, can be slid outs wardly from the body, the lever 14 moving awa from the path of the cam 23. The oil can replenished readily and the parts then slid back into place and resecured.

It will be noted that the withdrawal of the oil pan and the pump therein and their replacement can be eflfected without stop ing the operation ofthe machine with w ich they are used. Thus there will be no loss due to temporary discontinuance of production.

What is claimed is;

1. The combination with a machine to be lubricated including an operatin element,

of a lubricant an, and a pump in the pan for elevating lubricant from the pan, sai pan being slidable under the operating element and 1nto and out of the machine to move the pump into and out of operative connection with the operatitng element.

2. The combination with a machine to be lubricated including an operating element and. ineans for delivering used lubricant, of a lubricant pan, a pump therein for elevating lubricant from the pan, said pan being movable into the machine and beneath the operating element to receive lubricant from the delivering means and to place the pump into operative relation with the operating element, and being movable from under the operating element and from the machine to disengage with the operating element.

3. The combination with a machine having an operating element and a lubricating system including means for delivering used lubricant, of a lubricant pan, a pump therein for elevatin lubricant from the pan, said pan being mova le into the machine and under the operating element to receive lubricant therein including a s restrained lever and a piston connecte to the lever, said pan being movable into the machine to position the lever for actuation in one direction intermittently by the cam.

6. The combination with a machine to be lubricated including a rotatable cam, of a lubrlcant pan, a pump in the pan for lifting sald lubricant therefrom, said pump includlng a piston, a lever for moving the piston in one dlrection, and a spring for moving the lever and piston in the opposite direction, said pan being movable into the machine to receive used lubricant therefrom and place the lever in position for intermittent actuation by the cam in one direction against the action of the spring.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
